To aZZwz-omyz'tmag/ concern: p y j l Be it known'that l,W1LLiAM H.BANDs, a citizen of the United States, and a residentv of the borough ofSouthmont, in the county of Cambria and State of Fennsyl- Vania, haveinvented certain new andusetul Improvements in Fenders; and Ido herebydeclare the following to be a full, clear,l and exact description of theinvention, suchv as willenable others skilled in the art to which itappertains to -make and use thev same. l

My invention relates generally to a teni der which is particularlyadapted for use in connection with electric traveling cranes for thepurpose of pushing men'and materials from the tracks as the crane isbeing traversed thereon so that the wheels or other portions of theapparatus will not contact with them.

This fender is particularly adapted to prevent accidents to workmen whomay be on or about the crane runway and if one should be in the way ofthe moving apparatus, my fender will push him away with-` out damage.Ordinarily it is only the 'hands or the feet of the men that are likelyto be run over while the `rest of their persons is otherwise supported,so that the pushing action of my fender will merely displace the foot,hand or leg of the workman without causing him to fall and withouthurting him. My fender is also equally applicable to any kind of movingvehicle, such as, street cars, railway cars of various types, etc.

One of the particular features of my invention resides in itsapplication to an electric traveling crane provided with tracks havingwheel stops, which stops are ordinarily formed from plates of steel or acasting rmly secured to the ends of the track rails and extendingupwardly therefrom to contact with the wheels. An ordinary fender ifapplied to the carriage of a crane would be bent and damaged bycontacting with the stop. By means of my invention I obviate thisdifficulty and provide a stop which while operative underv all usualconditions is moved vaway from the wheel stop automatically as itapproaches it, in such a manner as to prevent its contact there-with.

My fender is preferably hinged to the crane carriage and is providedwith guides adapted to contact with inclined vslides adjacent to thetrack so that as the fender approaches the stop the two portions thereolopen and permity the wheel to contact with the stop without touching thefender. The fender is also provided with springs or aaaaaai i othermeans for closing together the parts f of the fender into operativeposition-as it moves away from the stop.

Where there is only onecranefon a runi waythis should be fitted withfenders on both sides, but where there areftwo cranes, Y

the fenders need only be on one side of each.

Having thus given ageneral description of my invention, I will now, ini`order to makev the matter more-clear;4 refer to the annexed sheet ofdrawings which form part ofthis specification andin which like`characters of reference refer to like parts.A

Figure l is a top plan view of a crane with my fender attached thereto:Figure 2v is a side elevation of Figure l; Figure 3 is a detail sideelevation of the tender and enough of the crane to show how it isattached, and Figure 4 is a perspective view of one half of one of theguard members of the fender. y

Referring now to the characters of reference on the drawings.y crane ingeneral; 2-are the tracks on which it is adapted to operate; S-are thecrane `runway girders which support the crane; 4-are the bumpers orstops secured at 4and to the ends of the crane rails` 2; -are theinclined slides adapted to open and'close the two-portions of thefender; 6-are the wheels of the 4crane carriage adapted to contact withthe stops 4 to limit the crane movement; 7*-are stationary U- shapedmembers sec-ured'to the cranecarriage to which the movable portions 8 ofmy fender are pivotally attached. The hinge members@ are provided on theU- shaped portion 7 and other `movable hinge members 10 are secured tothe moving parts 8 and co-operate there-with. These members have hingepinportions 11, as illustrated, which lit in corresponding socketsy inthe other hinge members. Springs l2 are provided, secured to theU-members 7 and adapted to contact with the moving portions 8 to keepthem in their normally closed positions as illustrated. 13--is a pinadapted to limit the movement of the springs 12. Outwardly projectingflanges 14 are provided at the lower edges of the movable members 8 androller guides 15 are rota-v l-indicates the tively mounted near theouter edge thereof to contact with the slides 5 to open the fender andprevent its contact with the stop 4:.

My fenders are each thus seen to be made of two similar parts pivotallymounted on a stationary portion and are adapted to be opened as thecrane nears the stops in such a manner that the 'fender does not contactwith the stop and as the crane moves away fromthe stop the fenderautomatically closes by the action of the springs, so as to immediatelycome into operative position again.

Although l have shown and described. my invention in considerabledetail, I do not wish to be limited to the exact and specic detailsthereof7 as shown and described, but may use such modifications in,substitutions for, or equivalents thereof, as 'are embraced within thescope of my invention or as pointed out in the claims.

l claim:

1. A fender comprised or two portions, each of which is pivotallymounted at one end, a guide on each portion and inclined slide-waysSecured to the track structure adapted to co-operate there-with, for thepurpose of separating said portions, whereby contact with the track stopis prevented.

2. A render comprised of a pair of portions with inclined surfaces, eachof which is pivotally mounted, guides on each portion, slides secured tothe track structure adapted to co-operate with said guides, and springsadapted to normally hold the two portions together. p

3. A crane fenderl comprising a fixed portion secured to the carriagethereof, hinges mounted thereon, a fender of tapering form composed oftwo similar portions separated in the. plane of the crane stop; saidportions` being provided` with hinges' adapted to cooperate with thehingeseforesaid, springs for normally holding the two portions together;guides on each portion, and inclined slides adapted to co-operatethere-with, to open and close the movable portionsof the fender toprevent contact thereof with the stop.

ln witness whereof l hereunto a-iix my signature;

VILLIAM H. BANDS.
